Rust has this, as well as some other nice ML-inspired[0] features, like structured bindings. That’s one thing I like about Rust: it fuses functional and imperative styles very naturally. [0] “ML” here meaning the family of languages including SML and OCaml, which inspired (to varying degrees) Haskell, Rust, some parts of modern C++, and surely others. Not “machine learning”.
